had been looking at the PRG leveling kit for a few months and tracking the price, hovering around $200 - 260. noticed the RTZ kit for $91 on Amazon one night whilst clicking random stuff on my phone, and boom I ordered it.
Specs:
3" polyurethane front spacer
2" rear shackles

Note: I prefer rear shackles to riser blocks with u-bolts. it seems to me that adding a spacer between the axle & spring seat will increase the tendency to "roll" the axle, thus turning the leaf springs into s-curves under acceleration/braking. Longer shackles just lift the whole rear end up away from the frame attachment point, without changing any suspension geometry. :nerd: So I went with the longer shackles here.

Installed with my buddy, took about 5 hours and 6 beers, working at a relaxed pace. I really enjoyed taking the front end apart to see how this is designed. based on all the race cars I've worked on, this appears to be a very burly suspension system, as it oughtta be!! >:D

Now the truck sits nice an high (but not too high.)

Drive quality was not affected in any way I can tell. this is my daily driver, and it handles just as well as ever. Negligible difference to mpg economy.

Looks good. Did my PRG lift Saturday with Bilsteins, rear spacers, and cam bolts.

Only problem I had was that the cam bolts were frozen in the LCA, so we needs a few more beers and ended up doing new LCA's.

Yeah that'll happen. I didn't do cam bolts in mine yet, but the wheels are slightly cambered after the install. Gonna take it for an alignment first.

With 3" in front you'll likely need camber bolts and you'll have coil bucket contact.

I have 3" spacers up front with camber bolts and SPC upper arms with the adjustable ball joint. Shop said easiest alignment he's ever done on a lifted truck. I used custom rear springs for lift and load. I tow a 4500 lb travel trailer.

poly 3" spacer. So these go between the top hat and the coil; a spring preload increase. And not a shock top spacer?

No change to ride quality, as far as I can tell.
Yes, the poly spacer goes above the shock, and some coil bucket contact can occur. Sometimes if I hit a speedbump too quick there's a clunk when the body bounces up and the front wheels drop down. Planning to get camber bolts soon.

That's how it sits on a trail, leveling kit installed. I skimmed way fewer rocks with the slight lift.
